How early is this SS collar tab?

I just purchased this Algemine SS collar tab, and was wondering how early it was. It has white and black braiding around it. The numbers are bullion, but the string is not. I was hoping someone could tell me when this style was in use.
Thanks

I assume my collar tab is a little earlier than the ones Friedrich posted. The bullion on the numbers is the same style. The only difference is the braiding around the edge of the tab, which is white and black, instead of bullion and black. Thank you to every one who has posted so far.
